Since Sony has announced limited shipping volumes between when the PS3 goes on sale in the US on Nov 17 and the end of the year, there are some determined people who have already started camping outside stores to ensure they get their hands on one on day one.
Since stores also only had guarantee of a limited number machines for day one, preorders were also limited at a number of stores (10 per store), like EB Games and GameStop.
Looks like if you’re not already in line then there’s probaby no chance of getting one on day one at this point.
